In the past months of playing Spiral Knights I've gathered quite some CE. I'm more into TF2 however, so I'm selling it.

Prices:
- 800 CE for 1 key
- 7.000 CE for 8 keys/ bill/ Strange Widowmaker.

A key may be replaced by 2.66 refined.

[CE Left: 7.000]

Add me if you want to buy some ;)

And above all; happy trading, folks!
